Lesson 1 DLIS File Import
There are two ways you can import *.dlisdata - File(s) import or
Selective DLIS import(Figure 14).
Figure 14 File(s) import dialog
File(s) importloads the header and the data, applies the family
assignment rules, and calculates statistics when loading to the buffer.
Selective DLIS importloads the header to the buffer and applies the
family assignment rules (quick load). When you transfer files to the
Project browser, it loads the data and calculates statistics.
This type of import is useful when working with large Wellbore image
files, or when you to view the content of the file. Imported data are dis-
played in the import buffer, where you can verify that all variables are
present (Figure 15).

After data are imported into the buffer, highlight the datasets to be
imported into the project and click the Blue Arrow to move them
into the Project browser(Figure 16).

Module 3 TVD Computation andIndex Dataset
This module covers how to compute a True Vertical Depth (TVD) vari-able and create an Index dataset.
The Index dataset creates a correspondence table using the reference
depth of each dataset. This step is necessary in order to link all the
datasets within a well. Without the Index, data cannot be displayed in
3D plots and some modules will not run.
Learning Objectives
After completing this module, you will know how to use:
deviation survey data to calculate TVD
the Reference Datasettool to create a correspondencetable.
Lesson 1 TVD Computation
This tool uses deviation survey data to calculate true vertical depth
(TVD), the offset of the well, and several additional references.
Running a TVD Computation
To perform a computation:
1. Select Techdata > TVD computation.
2. Insert the required families, as indicated in the figure, andclick Create. An empty True Vertical Depth window displays.

3. Drag-and-drop the deviation survey dataset into the Projectbrowseron the left side of the window, under the Wellstab.
A line appears for each well, with additional parameters. The
parameters are read directly from the well properties. In this
example, it is an on-shore well with an elevation of 90 feet.
4. Scroll across to the Methodfield on the right side of this
parameters line. You can use the drop-down options tochange the method used to calculate the TVD curve and
sampling rate of the new dataset.
5. ClickApply. A new dataset named TL_WellPathis createdunder Well1in the Project browser.
This dataset contains:
TVD - true vertical depth
TVDSS - true vertical depth sub-sea measured from the KB
XOFFSET - the offset in the X direction from the well
position, measured from sea level
YOFFSET - the offset in the Y` direction from the wellposition
TVDBML - true vertical depth below mudline, measuredfrom the earth's surface:
(TVDSS - water depth)
TIP: The names can be modified in the properties of
the method.

6. Remove Well1from the Wells list in the project navigationpane.
7. Repeat step 3 through step 5 for Wells 2, 3 and 9.
8. Drag-and-drop all three wells together in the navigation paneunder the Wellstab and calculate the TVD for each at the
same time.
Lesson 2 Correspondences Table
Creation
Without an Index dataset, you cannot display items in 3D, display 2D
plots according to various references, or work with specific modules.
Creating a Correspondences Table
To create a correspondences table:
1. Select Techdata > Reference dataset > Manual build.
2. Drag-and-drop one or more datasets into the Datasetsnavigation pane.
In this example, select two datasets:
MICP, containing MD and Core depth data
TL_Wellpath, containing MD, TVD and TVDSS data.
All the depth measurements in each well are displayed in the
corresponding column.
3. For each dataset, choose the curves to use in the Index
dataset and clickApply.A new dataset named Indexis generated from this operation. It
comprises allthe depth variables from the datasets present in
allthe wells used in the process.
4. Remove the datasets from Well1, and repeat the operations
for the other wells.

Module 4 Variables Management
Variables are series of data - alphanumeric, scalar curves or vector
arrays - arranged according to a chosen index or reference. Upon
import, each variable is assigned to a familyusing the Family Assign-
ment Rulestool. Each family has its own display properties, regard-
less of the variable name.
For example, any curve assigned to the Bulk Density family displays in
a linear scale, using a red color between the limits of 1.95 2.95 g/
cm3. If the curve has other units compatible with the family's unit, an
on-the-fly conversion is done, and the display respects the same limits.
In this instance, the limits are between 1950-2950 Kg/M3.
Aliasis a generic name for variables, but with an order of priority that
can be defined by a user.
Learning Objectives
After completing this module, you will know how to:
edit the Families database
import and export families

10. In the Edit familieswindow, click on one of the levels - User,Project, Company or Techlog- and view the Properties
window. The priority in display settings is User first, thenProject, Company, and Techlog, in that order.
In the Edit familieswindow, you can deactivate or activate the rules
for any level. Deactivating a level means that you will not use the set-
tings at that level. Instead, you will use the settings for the next level
down. Deactivating a specific level is useful when you need to gener-
ate a report or other specific output.
For example, gamma ray displayed with Techlogsettings is always
displayed with a baseline value of 75 for the area fill. If you have no
need for the settings, you can remove them from a baseline in the
User level.
Because users can use their own display settings, identical data may
be displayed in different ways. To maintain continuity, you can use
Project settings instead of your personal settings so that all plots in the
project are harmonized. The same logic follows for the Company level.
Creating a New Family
You also can create a new family at any level.
To create a new family:
1. In the Edit families tab, select one level: User, Project,
Company, or Techlog.
2. Click New .
3. In the window that displays, highlight the main family, family
and level in which to save the new family.TIP: Alternatively, you can add a new family to the
predefined list of Main families.
4. After creating a new family, go to the Propertieswindow and
define the display settings for the new family.
5. Click to validate and save the changes, and assign a
curve to your new family.
6. Right-click on a curve in the Project browser, and assign it
to the new family using the contextual menu that is displayed.

Creating LQC Datasets
To create Log Quality Control (LQC) datasets:
1. Select Techdata > Alias management > Alias inventory.
This opens the tool, and lists all the aliases that exist in the
Project browser.
2. Click to include specific aliases in the new dataset andclick OK.
DEN
DT
GR
NEU
This step reduces the list to only these four aliases.
3. For each well, select the curves to be included.
4. In the Propertieswindow, underAlias inventory, verify thatthe property Keep the original variable name in the
harmonised datasetis toggled to Yes.

Module 5 LogView
LogViewis a useful tool that allows you to display any variable pres-
ent in the Project browser. The actions available in LogVieware
classified by the type of action, and the actions available in the
dynamic toolbar depend on the object you select. The fixed toolbar
and mouse mode do not change.
Learning Objectives
After completing this module, you will know how to:
configure the appearance of LogView
create core image displays
build zonations
create plots in track
save and apply a layout.
Lesson 1 LogView Appearance
LogViewcan display any type of data, including log, zone, core
image, seismic, array data, and core measurements. LogViewis
accessed in several ways:

To display data, drag-and-drop one or more variables from the Project
browserto a LogView window. The variables for each family display
according to the parameters set in the Familiesdatabase.
These settings can be viewed in the Propertieswindow.
Figure 28 Menu bars in LogView
In addition to changing the curve color and thickness, tabs in the Prop-
ertieswindow allow you to change the scale of the plot, the datum, ref-
erence depth, and more.

Set the zoom by moving the mouse up or down while holding the
down the scroll wheel. If you have a mouse without a scroll wheel, set
the zoom by holding down theAltkey and the left mouse button while
moving the mouse up or down.
Figure 30 Sett ing the zoom and scale
To improve a layout, many options are available in the LogView Prop-
ertieswindow and the Variable Propertiesand LogView toolbars.
(Refer to the user guide for more information).
Among the available options are
Variable
management
Variable, family, and alias
Access to variables from a dataset accord-ing to a family or alias.
Variable
appearance
Limits horizontal and vertical axes, variable
position, boundaries, curve color, line thick-
ness, unit, and connection type.
Select the variables (they turn red) and go to
the Properties window to adjust the param-
eters.
Repeated variable
display
Display the same variable in a track multiple
times.This is particularly useful to simulate seismic
traces with a repeated display of synthetic
logs.
Wrap display Display the values of a variable not visible in
a track.
Text mode Display text values of a variable in a track.

Multiple variable
appearance
modification
Apply a modification to multiple variables at
the same time.
These properties can be modified simulta-
neously: Color, Font, Type, Thickness, Con-
nection, Marker (type and size), Scale, and
Type of Limits (Mnemonic, User, Variable)
Reverse variable
boundaries
Inverts variable boundaries.
Variable filling and
shading
Insert a color filling between a variable and
its right or left limit; insert shading between
the two curves.
Baseline Modify track appearance.
Adjust the zoom factor, display or do not dis-
play zones, modify the color of the trackbackground and its width, insert a track
name in the header, adjust the number of
vertical lines, select the color and thickness
of vertical lines and their scale (linear or log-
arithmic).
Grid increment
modification
As many as three grids can be displayed in
a track: the main reference grid, a second-
ary grid, and a tertiary grid.
Each has a user-defined increment, which
allows you to capture a greater or lesseramount of detail from the variables dis-
played.
Save layout and
layout properties
A LogViewlayout and its properties can be
saved and retrieved at a later date. Saved
layouts are saved in the Project Browser
under Layouts.
Apply layout and
properties to other
datasets/wells
When a LogViewis set up for a particular
well, its layout can be used as a model to
display other wells. The subsequent wells
display the same variables, all of which cre-ate a display using the same settings as
those of the original layout.
